microphone picks up the Sound of your claps‚ coughs‚ and the sound of that book knocked off the table. It produces a Small electrical signal which is amplified by the succeeding transistor stage. Two transistors Cross connected as a bi-stable multi-vibrator change state at each signal. This is a sound sensitive circuit‚ When sound is produced it is changed into electric energy through condenser mic and LED turns on. LED turns on sound signal and turns off automatically after few seconds‚ the LED on-time

which is great and all‚ but there are two major problems. First of all‚ the most degrees object are not at head level. Furniture and most of other things that can be easily tripped over and stubbed on are waist level or lower. Second of all‚ having vibrator motor constantly vibrating around head can be quite disturbing. Therefore‚ installing the device on the hand is the most effective way to mount it because the wearer can easily point it at anything they’re curious about and won’t be interfered by

EXPERIMENT NO-1 AIM- To determine the frequency of A. C. mains by using an electric vibrator. APPARATUS- Electric vibrator‚ table lamp‚ pulley‚ weight box‚ fishing cord‚ a. c. source. THEORY- when a cord of mass per unit length m is connected to the vibrating rod of the vibrator and stretched with a tension T‚ the cord vibrators in segments. If the length of the cord is then adjusted until the nodes are clearly marked‚ the frequency of the stretched string is the same as of the vibrating rod which

Site establishment Planning One of the key successes to most projects is in the planning preparation. It is important to establish the key members of the site team as soon as possible and then establish them on to the site. As much time as possible should be allowed for planning and preparation with the team on site. Planning includes various parts such as the completion of the network diagram‚ cash flow and labour preparation. Preparation Before starting anything‚ the site has to be fully

Carry out study of a Classical Guitar and write a report on its history‚ development and construction. The classical guitar‚ sometimes called the Spanish or nylon strung guitar‚ consists of a hollow body made with a top‚ back and sides constructed from thin pieces of wood carved and shaped to give the familiar traditional figure of eight shape. A long narrow piece of wood‚ called the neck‚ is attached to the body at one end and has‚ at the other end‚ a headstock to which are attached six tuning

Guide Questions What effect does increasing the tension have on the number of segment formation? Explain your answer. According to a theory‚ changing the tension will definitely change the number of segments. From equation three‚ the frequency is directly proportional to the number of segments and the tension and inversely proportional to the mass density and the length of the wire. Manipulating the formula to solve for the number of segments‚ n‚ is inversely proportional to the tension‚ thus
